Abstract

fetched live from OpenAlex

CaSO 4 and Ca(OH) 2 are the two main soluble phases in ash from the fluidized bed combustor (FBC) combustion of high-sulfur fuels with limestone addition. Their solubilities are of critical importance to several problems ranging from leaching to sorbent reactivation processes with liquid water. To determine these parameters, realistic models are necessary to estimate the activity coefficients of ionic components present. The current results indicate that the decrease of CaSO 4 solubility in the presence of Ca(OH) 2 is smaller than suggested in some earlier calculations, using more simplified assumptions. Experimental data from real FBC ashes have been obtained for comparison, and the current model predictions and experimental results are in excellent agreement.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
